There was a time – perhaps a decade ago, perhaps more – when the network was simply the network. It was routers and switches and cables and power. It was responsible for carrying data to and fro, and for acting as a hard wall gatekeeper that would prevent data from getting from one place to another.

As time went on, the network added more functions. It connected the network to the Internet, it measured traffic, it acted as a firewall, blocking traffic based on any number of criteria. It dabbled in security, as well.

All of that pressure has brought us to the place where it’s hard to find the right network device that does it all. That’s why, increasingly, IT is turning to network add-ons to help with concerns such as web traffic and cloud computing technology.

Why now?There’s been a dramatic shift in the way that network traffic moves over the past few years. As more and more organizations move away from a client-server model of operations, their existing network architectures tend to be a bit outdated and inefficient.

These add-on devices help to transition the old “tree” network architectures into a model that supports a flatter architecture that’s more in line with the needs of organizations relying on cloud computing and virtualization models.

Flattening the networkIn some ways, it’s all about flattening the network. The old network was multi-tiered, and needed to be. As network speeds increased from 10 Mb up to today’s 10GB and 40GB systems, the pipe has become bigger. Yet, the way that the network handles its traffic faces so many bottlenecks in the tiered network structure.

In many ways, it’s the mark of a shifting network philosophy, especially in the enterprise.

More savingsAnother reason organizations are turning to add-ons is to try to make their existing networks more efficient without having to invest in new infrastructure. Consolidation, performance monitoring, and optimization are all really methods used to extend the life cycle of existing equipment.

As time goes on, it will be interesting to see whether these add-ons continue to expand, or whether organizations find more appropriate network infrastructure models (i.e. flatter) that make better use of resources.

The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...

Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...

The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.

Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.

As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...

In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regulatory scrutiny and increasing consumer lack of trust in technology in general.
